Supplementing with Vit B12/Folate - how long before I feel better?

Hi, I have Hashi's .Lab results showed vit b12 was 353, and folate 6.6 - also noted MCV is 92. Researched forum, and found that these results suggest I am deficient in both. Started with Ferratin 400, and B12 5,000 ( the one that forum members recommend that is is best absorbed sublingually), and now take my Levo ot night, and those supplements ( along with 500 Krill oil and Vit D ) in the morning. I have also cut wheat out. Although I am starting to feel better, I wondered how long it takes for these changes to really make a difference? I have been supplementing for about a month now.Thanks
